Butt welding  Pipe fitting is a commonly used technique in welding that can either be automated or done by hand on steel pieces. Butt welding can also be done with brazing for GI and MS pipe and Fittings. It is used to attach two pieces of metal together such as pipe, framework in factories, and also flanges. A flange is something that either is internal or external that provided to strengthen a piece of material.In factories butt welding has shown how economical it can be for companies to use when building things out of metal. This is because if they wanted to make something out of metal without welding it together they would have to bend everything and reinforce the structure which costs more than welding the two pieces together.Butt welding is accomplished by heating up two pieces of metal, or applying pressure, or doing both of those.Penetration while welding the metal is important to maintain and with thin pieces of metal this is possible however, with thick pieces edge preparation may have to be done to prepare the metal. Full penetration butt welds are made when they are in the within the parent(bigger, stronger) metal.In butt welding the strongest welds will have the least amount of imperfections. To achieve this the heat input is controlled, which decreases the size of the weld.In commercial welding when this is done it also reduces cost but in order to maintain the strength of the weld double butt welds will be used. In butt welding there are two types used to achieve the specific welds and then there are also a variety of joints considered to be butt joints.
